Abstract

Aiming at improving the design and assembly efficiency of complex products in collaborative design, this paper proposes a parallel assembly model which is based on parallel computing. It divides assembly task into subtasks according to main branch in the virtual-link structure, and finally the subtasks run in parallel. This model supports large scale design, improves the speed and at the same time improves the computing resource utilization of collaborative design in Grid environment. A collaborative design prototype system based on Grid, which takes hybrid CSG/B-Rep model as geometric kernel, is developed to realize parallel assembly. Experimental results obtained from Lenovo DeepComp 1800 System are displayed and analyzed.
